And if more:Between DNA and RNA, there are three major differences: 1. DNA contains deoxyribose sugar, RNA - ribose, which has an additional, compared deoxyribose with hydroxyl group. This increases the possibility of hydrolysis of the group of the molecule, i.e. reduces the stability of an RNA molecule. 2. The nucleotide complementary to adenine, thymine in RNA does not, as in DNA and uracil - thymine unmethylated form. 3. DNA exists as a double helix consisting of two separate molecules. RNA molecule, on average, shorter and more preferably single-stranded. based on this, select the answer yourself)!
